In case of a valid revocation the mutually received goods, services and payments are to be returned. If you cannot return the recieved goods and services or can return them only in a reduced quality, you will be liable for compensation of the loss of value. [In case of surrendered goods a reduction of quality as might be expected if the goods were physically inspected in a store is acceptable]. You can avoid the liability for loss of value if you treat the goods not like an owner and refrain from any activity that may reduce the value. Items ready for shipment are to be returned to us at our cost and risk.
